Java SpringBoot Postgres remove rows

Help me please to remove the row in Postgres by clicking the Del button.
Maybe to link id in DB and id on the HTML page, but how?
Maybe I need to parse the HTML page and pass String id?
Any ideas will help me.
here is my database schema:
<table class="tmc">
<thead>
<tr>
<th>ID</th><th>TMC</th><th>SN</th><th>Owner</th>
</tr>
</thead>
<tbody>
{{#messages}}
<tr>
<td>{{id}}</td>
<td><span>{{text}}</span></td>
<td><i>{{sn}}</i></td>
<td><i>{{owner}}</i></td>
<th><form action="/remove" method="post">
<input type="submit" value="Del"/>
<input type="hidden" name="_csrf" value="{{_csrf.token}}" />
</form>
</th>
</tr>
{{/messages}}
</tbody>
#Entity
#Table(name = "message")
public class Message {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private Integer id;
private String text;
private String sn;
private String owner;
public Message() {
}
public Message(String text, String sn, String owner) {
this.text = text;
this.sn = sn;
this.owner = owner;
}
Rows are forming in database by:
#PostMapping("/main")
public String add (
#RequestParam String owner,
#RequestParam String text,
#RequestParam String sn, Map<String, Object> model) {
Message message = new Message (text, sn, owner);
if (text != null && !text.isEmpty() & sn != null && !sn.isEmpty() & owner != null &&
!owner.isEmpty()) {
if (!text.matches("^[0-9].*$")) {
messageRepo2.save(message);
Iterable<Message> messages = messageRepo2.findAll();
model.put("messages", messages);
} else
model.put("error", "ТМЦ не должно начинаться с цифры");
Iterable<Message> messages = messageRepo2.findAll();
model.put("messages", messages);
} else {
model.put("error", "Заполните все поля!");
Iterable<Message> messages = messageRepo2.findAll();
model.put("messages", messages);
}
return "main";
}

There are two issues with your html code:
it would be to let the form element outside the table
need to use <input type="hidden" name="xxx" value="{{xxx}}" /> in order to let it can pass parameter to your controller method
<form action="/remove" method="post">
<input type="hidden" name="_csrf" value="{{_csrf.token}}" />
<table class="tmc">
<thead>
<tr>
<th>ID</th><th>TMC</th><th>SN</th><th>Owner</th>
</tr>
</thead>
<tbody>
{{#messages}}
<tr>
<td>{{id}} <input type="hidden" name="id" value="{{id}}" /></td>
<td><span>{{text}}</span></td>
<td><i>{{sn}}</i> <input type="hidden" name="sn" value="{{sn}}" /></td>
<td><i>{{owner}}</i> <input type="hidden" name="owner" value="{{owner}}" /></td>
<td><input type="submit" value="Del"/></td>
</th>
</tr>
{{/messages}}
</tbody>
</table>
</form>

Show result by date that we pick - Play Framework

I have a page that show all lists from "dataLansia" table. Like this one :
http://i61.tinypic.com/fliwcm.jpg
And then, I want to make a little improvement. When I pick a date from that date input and I press 'Cari' button, the page show me only the result from 'dataLansia' table where the attribute of 'Tanggal Data' match with the date I pick before. How to do that ?
Here's my stuff (controller, model, view) :
public class Application extends Controller {
//the other code
public static void rekap(){
List rekapProfil=dataLansia.findAll();
render(rekapProfil);
}
}
public class dataLansia extends Model{
public String tensi;
public int guladarah;
public int kolesterol;
public double asamurat;
#Unique
public java.util.Date tglData;
#Lob
public String keluhan;
#ManyToOne(cascade=CascadeType.ALL)
public potensi lans;
#ManyToOne(cascade=CascadeType.ALL)
public lansia lansia;
}
public class lansia extends Model {
#Unique
public int idLansia;
public String namaLansia;
public int umur;
#Lob
public String alamat;
#OneToMany(mappedBy="lansia",cascade=CascadeType.ALL)
public Collection<dataLansia> dataLansia;
public String toString(){
return namaLansia;
}
}
#{extends 'Template/Dashboard.html' /}
#{set title:messages.get('rekap.title') /}
<div class="row">
<input type="date" name="rekapTgl.tglData.format('yyyy-MM-dd')" /> <input type="submit" class="btn btn-info" value="Cari" />

How to Get #Transient Values in HTML

I want to get #Transient values from HTML.I had tried #Basic,it creates entry in db. I need to get this value.
Pojo:
#Transient
private int dueAmount;
public int getDueAmount() {
return dueAmount = this.getPaymentTotal() - this.getBillAmount() - this.getDiscountTotal();
}
public void setDueAmount(int dueAmount) {
this.dueAmount = dueAmount;
}
Controller
#RequestMapping(value="/billByPatientId/{id}", method = RequestMethod.GET)
public List<Bill> getBillsByPatientId(#PathVariable("id") String patientId)throws Exception {
List<Bill> BillDetailsByPatientId = billService.getBillsByPatientId(patientId);
for(Bill b : BillDetailsByPatientId){
System.out.println(b.getDueAmount());
}
return billService.getBillsByPatientId(patientId);
}
Js
$http.get('/bill/billByPatientId/'+patientData.id)
.success(function (data, status, headers, config) {
console.log(data)
$scope.bills = data;
});
HTML
<table data-ng-show='bills.length > 0' class="table table-hover">
<thead>
<tr>
<th class="col-lg-1 text-center">Bill No</th>
<th class="col-lg-3 text-center">Status</th>
</tr>
</thead>
<tr data-ng-repeat="bill in bills">
<td class="text-center">{{bill.billNo}}</td>
<td class="text-right">{{bill.dueAmount}}</td>
</tr>
In my current code i get " dueAmount " value because of printing " dueAmount " in my Controller, otherwise values will be null.
How to do this ?

Property on model attribute set in one controller method is not available in another controller method

Following contains the code inside my controller class , i am using the method public String getRegistrationForm(Map model) to return a jsp-page with a spring form on it , in this method i am setting userTab.setIsMfaEnabled(new Boolean(true)) , upon submitting the form the method :

jsp in another jsp struts 2

1st problem : i have a jsp in which there are two tabs ,for the second tab i have included the struts include tag. When i open the second tab and performs the action the second tab form values are not passing to the action.
2nd problem : in the select tag i have populate the list but it is coming as prepopulated means all the options are coming as selected="selected"

Well, the code is grown again :)
Start by :
changing your ArrayList declarations to List (in both beans, and regenerate getters and setters);
changing the way you get the Request, the Response and the Session, by using Struts2 Aware s interfaces (and their setters, with code inside)
Then if it still doesn't work, describe a little better what do you mean by "values are not passing to Action", and consider posting your interceptor stack config.
Hope that helps...
